Quote from NKNY:
Hi Walt...
If the first stock of the pair is a buy IE: ko/pep ...if KO is a buy , rsi for the pair should be under 30. in other words the ratio is oversold... ko has been weak lately in relation to pep...
Nick
Got it!
With KO being weak, the RSI of the pair will be low, and the expectation for a mean reversion will have KO going stronger, buy KO, short PEP.
Thanks Nick.
