SMH Put Spread 分析

I. What is a Put Spread (Bear Put Spread)? How to Operate It?

Its standard operation is: Buy a Put with a higher strike price, and simultaneously sell a Put with a lower strike price but the same expiration date.

Operation Formula: Buy Put A (Higher Strike) + Sell Put B (Lower Strike)

Cost: Your actual cost = Money paid for buying Put A - Money received from selling Put B (thus the cost is lower).

Maximum Loss: Limited to the net premium you pay.

Maximum Profit:(Strike Price A - Strike Price B) - Net Premium. When the stock price falls below the lower strike price B, the profit is locked and will no longer increase.

II. For SMH, How Should We Choose Parameters Now?

Currently, SMH's price is around 569.69. Based on the current sharp decline pattern, we can design two plans with different levels of aggressiveness for your reference:

Plan 1: Conservative/High Win Rate (Follow the current downtrend, take profit)

Expiration Selection: It is recommended to choose options expiring in around 25 to 45 days (e.g., expiring in mid-July 2026). This timeframe allows the market time to digest further while not letting time value (Theta) decay too quickly.

Strike Price Selection:

Buy (Buy Put): 570 or 560 (at-the-money or slightly out-of-the-money, close to the current price, starts making money immediately if the decline continues).

Sell (Sell Put): 520 or 510 (near important previous support levels).

Characteristics: As long as SMH continues to decline and oscillate below 520, you can achieve the maximum profit.

Plan 2: Aggressive/Small Bet for Big Gain (Bet on a complete breakdown)

Expiration Selection: Short-term options expiring in 14 to 30 days (e.g., expiring in late June 2026).

Strike Price Selection:

Buy (Buy Put): 550 (out-of-the-money, betting on continued momentum-driven selling).

Sell (Sell Put): 500 (a major integer level, strong support).

Characteristics: Extremely cheap cost. If the semiconductor sector experiences consecutive sharp declines in a short period, this combination can double in value very quickly. However, if SMH stops falling and rebounds at 550, this combination will face a total loss of the premium.

III. What Should You Refer to When Making Decisions?

Before finalizing the strike price and expiration date, you need to closely monitor the following three reference indicators on TradingView:

Reference Moving Average Support (Look at the main chart): The 200-day moving average (SMA 200) you just called up is the most important reference. Check where the 200-day line is currently. The low strike price Put you sell (Sell Put) is best set at or below the 200-day moving average support level. Because when the stock price falls to the 200-day line, it usually encounters strong support and rebounds, making it the safest place to set the bottom.

Reference VIX Fear Index (Look at the sub-chart): You have already pulled up the VIX below. The current VIX has shown a significant spike (up nearly 40% to 21.50). A high VIX means options across the entire market are expensive (high implied volatility).

Pitfall Avoidance Guide: Precisely because options are so expensive now, simply buying a Put would be severely "ripped off" (buying at a volatility peak). However, a Put Spread involves "one buy and one sell". The sold Put also benefits from the high premium brought by high volatility, which can offset part of the cost. This is the core reason for using a Spread instead of just buying a Put in the current market.

Delta Value (Look at the options chain): When opening the broker's options chain, observe the Delta value of the Put you intend to buy. It is generally recommended to buy a Put with a Delta between -0.4 and -0.5, and sell a Put with a Delta between -0.15 and -0.25. This ratio offers the best balance between win rate and risk-reward ratio.
