Weekend Theta

There's evidence of a small edge, but it's controversial. The edge is small and easily consumed by transaction costs and occasional large gaps. It works best as a supplement to other strategies, not a primary approach.

Yes, if you use defined-risk structures. Iron condors, iron butterflies, and credit spreads are TFSA-eligible. Naked short options are not permitted in TFSAs.

Typical gains are $10-20 per contract on a successful trade. With 5 contracts, that's $50-100 per weekend. But remember losses can be $50-70+ per contract on bad weekends.

Skip them. An extra day means more gap risk without proportionally more theta. The risk/reward worsens significantly on long weekends.

You need liquid weekly options. XIU ETF is best for index exposure. Major banks (RY, TD, BMO) have the most liquid options among individual stocks. Verify weekly options exist before trading.

Track every trade: credit received, decay captured, gap impact, P&L. After 20+ trades, calculate win rate, average win, average loss, and profit factor. If profit factor < 1.3 after costs, the edge may not be sufficient.

Generally yes for consistency. But you can adapt: iron butterflies in very calm, high-IV environments; iron condors normally; skip entirely in high-risk environments. Keep a default and vary based on conditions.

Don't enter the Friday trade. Weekend theta requires Monday exit discipline. If you can't commit to Monday morning, skip that weekend. Never enter hoping you'll 'figure it out' Monday.

If you're still within your profit range (inside breakevens), exit and take the smaller profit. If you're at small loss territory, still exit - the weekend trade is complete. Don't hold hoping for improvement.

2-4 underlyings is reasonable. Enough to diversify sector risk, not so many that you can't monitor properly. XIU + 1-2 bank stocks + 1 energy stock is a good mix.

Use your position's gamma and the expected gap (based on the stock's volatility and historical weekend gaps). Gap Cost ≈ |Gamma| × Gap² / 2. Compare this to expected theta to see if the trade has positive expectancy.

Partially. The edge has shrunk over time as more traders exploit it. However, it persists because: (1) gap risk deters large players, (2) transaction costs make it uneconomical at scale, (3) it's labor-intensive for small gain. The edge exists but is small.

You need Friday close and Monday open option prices with bid-ask spreads. Use realistic fill assumptions (between mid and natural price). Calculate P&L per weekend. The challenge is limited sample size (~50 weekends/year) and expensive option data.

Yes. On 'green' weekends (no events), you can tolerate higher gamma (tighter strikes, butterflies). On 'yellow' weekends (minor events), reduce gamma (wider strikes, condors). On 'red' weekends, skip entirely.

Yes. It can supplement a broader theta harvesting or volatility selling approach. Consider it as one tool in a portfolio: weekend theta on calm weekends, event volatility around earnings, gamma scalping in trending markets. Diversify across time horizons and strategies.
