formula that searches an array

On the morning of the Ex-Dividend Date, dividend stocks typically fall from the price the day before the Ex-dividend date by the amount of the declared dividend. The stock price then recovers back to the price (equals or exceeds) on the day before the Ex-Dividend Date, where that may take a day or many days but typically only a few days.

I need a formula that reviews a table of historical prices and supplies (in cells T5 and T6 inside the Thick Box Borders) the number of days it takes for the price to recover. I need for the formula to also supply that number from a specific ticker symbol, where the prices are organized by ticker symbol.

The formula I have (in cell T5) uses AGGREGATE, INDEX, MATCH, and ROW. It performs the first part (Days To Recover) but not the second part (specific to a Ticker), and thus does not work for a large table with many prices for many different Tickers.

See workbook attached.

I need help fixing that formula.

Thanks for your help!
