Adjusting close.

Dividend multiplier for adjusting close: (Close(T-1) - d)/Close(T-1) where d is the dividend.
Splits adjusting close: Close(T) * 1/N Where N is the split ratio.

Sharpe ratio

Daily return: (new_price - old_price)/old_price
Excess daily return: (daily_return - base_return) e.g. base_return for risk free rate at 4% would be 0.04/252 where 252 is number of trading days.
Sharpe ratio: √252 * average(excess_daily_return) / standard_deviation(excess_daily_return)
