MUMBAI: Dalal Street’s primary market entered high gear on Thursday as institutional and retail participants mobilized capital across multiple tranches, led by the high-profile tonbo imaging and bonfiglioli ipo pipeline alongside customer experience major Fusion CX. The unprecedented convergence of six concurrent public offerings across mainboard and SME segments underscores deep liquidity reserves, even as secondary indices face macro fluctuations driven by offshore monetary cues.

  • Concurrent Issues: Six public offers remain actively open for public bidding across mainboard and SME boards this Thursday.
  • Deeptech Interest: Tonbo Imaging commands robust grey market traction driven by its domestic defence electro-optics and thermal imaging capabilities.

  • Mega Pipeline: The current supply rush arrives right before the landmark Rs 30,000 crore Jio IPO scheduled for late October.

Tonbo Imaging: High-Precision Defence Tech Commands Dalal Street Focus

Bengaluru-headquartered Tonbo Imaging has taken center stage in the current issue roster, leveraging its niche position as an indigenous developer of electro-optical and thermal imaging payloads for global aerospace and autonomous systems. The Rs 1,150 crore offering features a balanced mix of fresh capital raise and an offer-for-sale (OFS) component, with proceeds designated towards expanding domestic chip-level sensor packaging facilities and international defense sales pipelines.

Market observers note that Tonbo’s proprietary sensor architecture positions it advantageously against traditional legacy imports. Even as global macro signals remain cautious after the Nasdaq Slumps 2% as Hot US Inflation Data Ignites Federal Reserve Rate Hike Fears, domestic high-conviction defense electronics continue to command premium multiples from institutional desks.

  • Capital Allocation: Rs 420 crore allocated to expand advanced optical assembly infrastructure.
  • Export Leverage: Over 60% of revenues derived from sovereign defense contractors across Europe and Asia.
  • Operating Margin: Maintained FY26 annualized operating EBITDA margins comfortably above 24%.

Bonfiglioli and Fusion CX: Industrial Capital Goods vs. Digital Business Services

Italian engineering giant’s domestic subsidiary, Bonfiglioli Transmissions, presents a pure-play bet on India’s capital goods expansion and renewable infrastructure push. Generating steady cash flows from industrial gearboxes and wind turbine pitch drives, the company’s Rs 1,800 crore offer appeals directly to long-only institutional portfolios hunting for non-cyclical manufacturing assets with robust return on capital employed (ROCE).

Simultaneously, Fusion CX represents the enterprise services spectrum, capitalizing on digital transformation mandates and omnichannel customer engagement. While enterprise software and IT solution providers have seen renewed operational interest—as reflected when Nifty IT Soars 4% as TCS, Infosys and Coforge Spark 2,000-Point Rally: Key Catalysts Behind Tech Surge—Fusion CX seeks to fund international delivery hubs across Southeast Asia through its public float.

“The simultaneous arrival of precision engineering like Bonfiglioli and enterprise service players like Fusion CX gives portfolio allocators a balanced spread across traditional industrial and new-age digital cash flows.” — Sunita Aggarwal, Equity Strategist, Mewar Equities

  • Bonfiglioli Capacity: Industrial capacity utilization stands near 82% across Chennai and Pune facilities.
  • Fusion CX Client Base: Over 180 active enterprise accounts with net revenue retention exceeding 112%.
  • Debt Profile: Both entities maintain conservative debt-to-equity ratios below 0.35x.

Zetwerk Anchor Triumph and Day 1 Inflows Elevate Overall Market Sentiment

Lending massive institutional credibility to Dalal Street’s current IPO feast, contract manufacturing unicorn Zetwerk Manufacturing concluded an explosive anchor book round, mobilizing Rs 2,251 crore ahead of its retail opening on October 15. The anchor allocation list reads like a global financial directory, with BlackRock, Goldman Sachs, Nomura, Abu Dhabi Investment Authority (ADIA), and top-tier domestic mutual funds scooping up their respective maximum allowable quotas.

This formidable institutional backing has dramatically spilled over into Day 1 bidding metrics. Across both mainboard counters and specialized issues like Shellz India, Qualified Institutional Buyers (QIB) and high-net-worth individuals (HNIs) demonstrated decisive early commitment, dispelling liquidity fatigue worries.

“When global tier-1 sovereign entities absorb large anchor books within hours, it validates the structural durability of Indian supply-chain manufacturing assets on the global stage.” — Vikram Sethi, Managing Director, Axis Institutional Equities

  • Anchor Tally: Rs 2,251 crore gathered from 48 institutional funds at the upper price band.
  • Sovereign Participation: Strong bids from Middle Eastern and North American long-term pension mandates.
  • Mainboard Spillover: Retail bid application rates surpassed 0.85 times within the first two hours of opening.

Grey Market Premium Trends and Merchant Banking Strategy Ahead of Jio IPO

Grey Market Premium (GMP) readings across unofficial trading hubs in Rajkot, Ahmedabad, and Mumbai indicate sustained investor appetite. Tonbo Imaging is commanding an unofficial premium of Rs 125–130 per share (+28%), while Zetwerk maintains steady grey trades near Rs 200 (+31%). Bonfiglioli Transmissions and Shellz India are similarly logging double-digit premiums over their respective upper price bands.

Investment bankers highlight that underwriters are deliberately pricing these multi-sectoral mid-cap and large-cap issues with demonstrable ‘money left on the table’. This disciplined pricing strategy is vital to ensure broad-based primary liquidity ahead of the unprecedented Rs 30,000 crore Reliance Jio IPO scheduled to open its doors on October 21.

“Merchant bankers are actively avoiding peak-cycle valuations. Leaving money on the table ensures successful listings and preserves market appetite for mega-issues lined up later this month.” — Devendra Chundawat, Partner, Lake City Merchant Banking

  • Top GMP Performer: Zetwerk commands the highest absolute grey premium at Rs 200 per equity share.
  • Valuation Discipline: Price-to-earnings multiples for the active issues remain 12-15% below comparative listed peers.
  • Listing Timelines: T+3 settlement protocol will see all active offerings listing between October 20 and October 23.

Investor Takeaway: Risk Profiling, Quota Allocation, and Listing Strategies

For retail and non-institutional investors navigating this multi-issue feast, capital allocation requires strict adherence to balance-sheet fundamentals. While Tonbo Imaging offers unmatched deeptech defense scarcity value and Bonfiglioli provides stable cash generation, investors should closely track working capital cycles and post-listing lock-in schedules for pre-IPO venture funds.

Wealth managers advise spreading application lots across diverse household demat accounts to optimize mainboard allotment probability under SEBI’s randomized draw mechanism, while reserving contingency liquidity for late October’s historic telecommunications offerings.

“Selective bidding based on EBITDA conversion and reasonable debt levels is paramount when six issues vie for identical liquidity simultaneously.” — Meenakshi Vyas, Portfolio Manager, Mewar Wealth Advisory

  • Diversified Bidding: Splitting funds between defensives (Bonfiglioli) and high-growth deeptech (Tonbo) minimizes portfolio sector concentration.
  • UPI Mandate Vigilance: Investors must approve UPI blocking mandates prior to 5:00 PM on closing days to prevent application rejection.
  • Listing Day Strategy: Pre-set stop-loss levels remain crucial to navigate expected opening-day volatility.
