Here on the daily chart you can easily see the case for put options if stock closes below yellow line. There is one lower support on a line chart (dashed line connecting closing prices). For the bigger picture, see a long term monthly chart.
Citigroup stock can head down to 30, up to 60. Keep watch on the daily RSI. Right now indicators are leaning towards puts.
