What are BIIB's key support and resistance levels?
The key levels table on this page lists the live MA25 and MA99 moving averages plus the 52-week high and low, with the distance from the current price. Traders commonly treat a rising MA25 as first support in an uptrend and the 52-week high as the nearest overhead resistance.
Is BIIB overbought or oversold?
Check the RSI(14) reading in the stats grid above. Above 70 is conventionally overbought and below 30 oversold, but in a strong trend BIIB stock can hold an extreme reading for weeks, so RSI alone is a weak trigger.
How should I size a BIIB trade?
Size off your stop distance rather than a fixed share count: decide the maximum you are willing to lose, divide it by the distance from entry to stop, and that is your position size. The position size calculator on this site does the math for you.
