I'll look at RDDT's option chain to analyze put premium yields across different strikes and expiries. Let me first check the current stock price and then fetch the options data.The stock is trading around $182.50 (based on the ATM options). Let me now compute the put premium yields. I'll extract the relevant put data and calculate annualized returns.I need to use existing dataframe IDs. Let me load some data first to create a valid DataFrame ID context, then run the compute.Here is the RDDT put premium yield analysis. RDDT was trading at ~$181.18 as of July 17, 2026.

RDDT Put Premium Yield — Annualized IRR (as of Jul 17, 2026 | Spot: $181.18)

Key observations:

• The 100 strike offers materially higher yield than 90 strike across all tenors — roughly a 200–500bp premium, reflecting closer proximity to the money.
• IRR sweet spot at the 100 strike: The Mar 19 '27 expiry (~8 months) offers the best mid-market IRR at 12.0%, with a tight bid/ask range (11.0–13.0%).
• 90 strike IRR peaks at ~9.5% at the Mar 19 expiry as well.
• Very short-dated (1–8 day) puts are essentially worthless at both strikes — the stock would need a catastrophic ~50% move to put them in the money.
• IVs are extraordinarily high (79–441%), which inflates option premiums and thus the put-write yields. This reflects the market pricing in extreme tail risk for RDDT.
• Wide bid/ask spreads in many tenors, especially the 90 strike, mean actual execution yields may differ meaningfully from mid. The 100 strike generally has better liquidity.

Good question. The IRR figures above use strike price as the denominator — which assumes the position is cash-secured (CSP). You put up the full $9,000 (90 strike) or $10,000 (100 strike) per contract as collateral and earn the premium against that.

If you were to run this on margin (i.e., naked puts in a portfolio margin account), the capital requirement is typically ~15-20% of the notional. That would roughly 5x the IRR — for example, the Mar '27 100P at 12.0% mid would become a ~60-80% IRR on margin. However, those are nominal returns before considering the leverage risk.

Let me recalculate showing both denominators side by side.Here's the breakdown with both methodologies (spot: $181.18, 20% margin assumed):

Denominator logic: - CSP IRR: Premium ÷ full strike collateral ($9,000 or $10,000 per contract), annualized — these are the conservative cash-secured numbers. - Margin IRR: Premium ÷ ~20% margin requirement (~$1,800–$2,000 per contract), annualized — approximates a portfolio margin / naked put scenario. Actual margin will vary by broker and account.

In practice, most traders selling puts at strikes 50% OTM ($90–$100 on a ~$181 stock) are running them on margin. The CSP numbers are the floor; the margin numbers are what you'd actually realize on capital employed — high double digits at the sweet spot, but with the attendant tail risk that made those IVs 80%+ in the first place.

All three strikes, spot $181.18, 20% margin assumption:

Strike comparison takeaways:

• 90 strike — Lowest absolute premium, widest bid/ask, most erratic across tenors. IRR peaks ~9.5% CSP / ~48% margin at Mar 19, but liquidity is thin and the bid-side is often zero in near dates.
• 100 strike — The balanced play. 10–12% CSP across the 4–8 month range, bid/ask is tradeable, and it's a clean ~45% discount to spot.
• 110 strike — Best CSP IRR at 13.8–14.2% in the Nov–Mar window. Only a ~39% discount to spot, so higher probability of being tested, but the yield curve is flatter and more consistent across tenors. This is where the premium really starts to scale — the 110P collects ~$10.23 for Mar '27 vs $8.08 for the 100P and $5.78 for the 90P.

Risk/reward gradient is clean: every $10 closer to spot roughly adds 1.5–2.5 points of CSP yield, at the cost of breaching ~5 percentage points closer to the money. The 110 strike essentially gives you an extra ~400bp of CSP yield over the 90 for taking on that incremental proximity risk.

RDDT Put Premium Yield — CSP & Margin IRR

Spot: $181.18 | ⚠ = zero bid (bid size 0) | CSP = cash-secured | Margin assumes ~20% requirement

Liquidity note: The 90 strike has zero bids through the first month and thin sizes beyond. The 100 strike is tradeable from ~1 month out. The 110 strike is the most consistently liquid across the curve, with the Nov–Mar window offering 13–14% CSP / 66–71% margin IRRs with real two-sided markets.

Yes — every IRR in the table above is on the mid price (average of bid and ask). For strikes where the bid is zero and bid size is 0 (marked ⚠), the mid is effectively just half the ask, so those IRRs are overstated relative to what you'd actually get as a seller.

Let me show the full bid/ask IRR range so you can see the realistic execution band.## RDDT Put IRR — Bid → Ask Range (CSP)

Spot: $181.18 | Sell at bid, buy at ask — as a put seller you capture the bid side

The real takeaway: for any expiry where the bid is non-zero (roughly 1-month+ for the 100/110 strikes), you're capturing 70–85% of the mid IRR at the bid. The 110 strike Nov–Mar window gives you a tight 12–15% CSP bid-side range without needing to rely on mid fills. The 90 strike remains the weakest — wide spreads and the bid-side CSP barely cracks 8–9% even at the sweet spot.

At the Oct 16 90P, the mid in my table was $1.13, and the bid/ask was $0.65–$1.61.

A limit of $2.00 implies you're trying to get above the ask. The current market is $0.71 bid / $1.355 ask (looks like the chain has moved slightly from when I pulled it earlier). If you fill at $2.00, let's compute:Your $2.00 limit → 8.9% CSP / 45% margin IRR. That's actually higher than my earlier mid estimate (5.0% CSP), since you're targeting well above the ask.

But here's the issue — the current market is $0.71 bid / $1.36 ask. Your $2.00 limit is roughly 47% above the ask. That order is unlikely to fill unless the underlying drops or vol spikes materially. At the current bid you'd be looking at 3.2% CSP / 16% margin — and even the mid is only 4.6%.

If you want ~9% CSP IRR on the 90 strike, you'd need to go out to the Mar '27 expiry where the bid itself supports 8.5% and the mid is 9.5%. For October, the 110 strike bid-side gives you 8.8% CSP right now without stretching above the market.
