Understanding RLYB Options Greeks

When trading Rallybio Corporation Common Stock options, the Greeks help you understand how the option price will change:

Delta (Δ)

How much the RLYB option price moves when the stock moves $1. A delta of 0.50 means the option gains $0.50 for every $1 stock increase.

Theta (Θ)

Daily time decay of the option. RLYB options lose value each day as expiration approaches, even if the stock price stays flat.

Gamma (Γ)

Rate of Delta change. Higher gamma means Delta moves faster, making near-ATM RLYB options more responsive to price changes.

Vega (ν)

Volatility sensitivity. When Rallybio Corporation Common Stock's implied volatility rises, high-vega options become more valuable.

RLYB Options FAQ

To buy RLYB (Rallybio Corporation Common Stock) options, you need a brokerage account with options trading enabled (like TD Ameritrade, E*TRADE, or Robinhood). Search for RLYB options, select your desired strike price and expiration, choose call or put, and place your order. Always understand the risks and consider starting with paper trading.

The optimal expiration depends on your strategy. 30-45 day expirations offer a good balance of time value and theta decay for most traders. Shorter expirations (7-14 days) have higher gamma but faster time decay. Longer expirations (60-90+ days) cost more but give the trade more time to work.

Use our options search tool to see current RLYB implied volatility levels. Compare the IV to historical averages to determine if options are relatively expensive (high IV) or cheap (low IV). High IV often occurs before earnings or major events.

ITM (In The Money) RLYB options have intrinsic value — calls where strike < stock price, puts where strike > stock price. They're more expensive but have higher delta. OTM (Out of The Money) options are cheaper but have lower probability of profit. ATM (At The Money) options have strike ≈ stock price and highest gamma.
