Implied volatility (IV) is the size of the moves that option prices assume, stated as a yearly percentage. Think of it as the weather forecast built into the option price. MRVL options expiring Oct 16 carry 61.1% IV at the money. That points to a typical daily move of about ±$10.79 (3.8%).
Each strike has its own IV. Plotted together they make a curve called the smile. When one side sits higher than the other, that tilt is called skew.
Calls 10% above today's price carry 65% IV. At the money it is 61%, and puts 10% below carry 61%. Traders are paying extra for upside, which often happens around takeover rumours or a short squeeze.
Term structure is the at-the-money IV for each expiry date, from the nearest to the furthest. The circled point is the Oct 16 expiry you picked.
Realised volatility is the weather that actually happened: how much the stock really moved, on the same yearly scale. Comparing it with IV shows whether options look expensive or cheap.
Options price in 61% volatility. Over the last 20 trading days, the stock actually swung at a 55% yearly rate (78% over 60 days). Options are pricing more movement than the stock has actually had. Some extra is normal: it's what option sellers get paid for taking the risk.
The curve slopes upward, from 61% for Oct 16 to 66% for Jan 19, 2029. This is the calm, normal shape. More time leaves more room for surprises, so longer-dated options carry more volatility.
