Should I sell my stocks when the stock hits a 52-week high in order to “Buy Low, Sell High”?
You asked for advice, so I'll offer it.  Trying to time the market is not a great strategy unless you're sitting in front of a Bloomberg terminal all the time. Another person answering your question suggests the use of index funds; he's likely to be right. Look up "asset allocation."  What you want to do is decide that you want your portfolio to contain, for example: If one of your stock holdings goes up far enough that you're out of your target asset allocation ranges, sell some of it and buy something  in another asset class,s so you're back in balance.  That way you lock in some profit when things go up, without losing access to potential future profits.  The same applies if something goes down; you buy more of that asset class by selling others. This has worked really well for me for 30+ years.
