BTI at my buy value area

I have calculated a buy value at roughly $36 (fair value based on earnings forecast minus 20% margin of security).
Now we are at this price.
Chart is in the main volume cluster but is falling like the entire sector (PM and MO have the same beta - volatility - at the moment)
BTI is plus affecting now by the fear of american investors due to the falling of pound sterlin and voices are telling about a possible cut in USD dividend.
Maybe usd dividend could return from 7% to the 5% which is the tobacco sector's dividend avarage. MO offers higher dividend at the moment but its economics and fair value are not in line with my strategies.
Looking the history, escluding the 80s, BTI did not performe bad during the falling of pound sterlin, and never a cut of its dividend in a big shot.
Tobacco sector is my preferred in line with the actual economic cycle, drop is good for buying lower, cash flows are strong and people will continue to smoke even during the recession.
