Synthetic Long Stock

Capital efficiency is the main reason. Buying 100 shares of SPY at $580 costs $58,000. A synthetic requires only about $10,000-$15,000 in margin while providing the same dollar-for-dollar exposure. This frees up capital for other investments or simply requires less of your account. The tradeoffs are: you don't receive dividends, you need to roll periodically, and you need margin approval.

You lose money just like a stock owner - dollar for dollar. If SPY drops from $580 to $550, you lose $3,000 per synthetic (30 points × 100). There is NO downside protection. The short put obligates you to buy at the strike price regardless of how far the stock falls. You could also face margin calls requiring additional funds or forced position closure.

No. Only actual stockholders receive dividends. However, expected dividends are already priced into the options through put-call parity - the call is cheaper and the put is more expensive by approximately the dividend amount. For high-dividend stocks, this makes synthetics less attractive than owning stock.

Typically very minimal - usually a small debit of $0.25-$1.00 or sometimes even a small credit. This is because you're paying for the call but receiving premium for the put, and they roughly offset. The exact cost depends on interest rates and expected dividends. However, you still need significant margin for the naked put.

No. IRAs do not allow naked (uncovered) put selling, which is a component of synthetic long. The short put creates an obligation that could exceed the account value, and IRAs cannot use margin. You can use other bullish strategies in IRAs like long calls, call spreads, or cash-secured puts.

If maintaining a long-term position, roll at 21-30 DTE to the next month. This balances time decay (minimal for synthetics) against roll costs and gamma risk near expiration. If the stock has moved significantly (>5%), consider rolling to the new ATM strike to maintain true 1.0 delta characteristics.

Reg-T margin is typically 20-25% of the underlying value - straightforward but capital-intensive. Portfolio margin is risk-based and often 50-75% lower, but requires $125,000+ account minimum. For active synthetic traders, portfolio margin significantly improves capital efficiency.

Both have approximately 1.0 delta and minimal theta decay. Key difference: Synthetic has unlimited downside risk but requires less capital (margin only). ZEBRA has defined maximum loss (the debit paid) but requires more upfront capital. Choose synthetic for capital efficiency; choose ZEBRA for defined risk.

Depends on stock price. Above strike: call is ITM and exercised (you buy 100 shares at strike), put expires worthless. Below strike: call expires worthless, put is assigned (you buy 100 shares at strike). At strike: both options likely expire worthless. In all cases, you either end up with stock or expired options.

Size based on NOTIONAL EXPOSURE, not margin requirement. If you'd normally buy $50,000 worth of stock, use the equivalent synthetic (about 86 shares worth for SPY at $580 = 1 synthetic). Don't let low margin requirements tempt you into oversized positions - the risk is the same as owning that much stock.

Synthetics provide market (beta) exposure using ~15-20% of notional as margin, freeing 80%+ of capital for alpha-generating strategies. For example: $1M synthetic S&P exposure requires ~$200K margin, leaving $800K for hedge funds, alternatives, or active strategies. The combined portfolio targets market returns PLUS alpha from freed capital.

Each roll is a taxable event - closing one position and opening another. Gains/losses are typically short-term since positions are held <1 year. Consider SPX synthetics for Section 1256 treatment (60% long-term / 40% short-term regardless of holding period). For high-volume trading, consider Section 475 MTM election.

Compare synthetic pricing to stock price plus financing costs. If synthetic is cheaper than stock minus expected carry, arbitrage by buying synthetic and shorting stock. If synthetic is expensive, buy stock and sell synthetic. These opportunities are rare and typically require institutional execution capabilities.

The short put may be assigned early, especially before ex-dividend dates when the put is deep ITM. The put holder might exercise to capture the dividend. Monitor positions closely near ex-dividend dates. If assigned, you simply own stock at the strike price - not necessarily bad, just unexpected timing.

Rising rates benefit existing synthetic longs (positive rho) - the position becomes worth more. Falling rates hurt existing positions. However, the impact is modest for typical holding periods. For LEAPS synthetics, rho impact is more significant. In rising rate environments, synthetics become increasingly attractive versus stock ownership.
