Data Tracking Using Excel is pretty much a must when running an averaging strategy over a long period of time, especially when running scenarios and "what-if" formulas in various price targets and timelines.
It's also handy for tracking book value vs current trading price and price taeget calculations based on Price To Sales ratios, current and historical.
Currently shares are trading under book value but the stock has a chance to get back up there based on latest report and (maybe) the acquisition news being clarified.
I have seen folks reverse calculate shareprice targets based on expected future market cap values but I'm not a fan of that approach.
You can Google "open source free download excel" if you want something that works and is free.
