Long term you need not do anything if you hold decent business
(strong cash flow, reliable revenue stream, low debt etc..)
yes there maybe a market correction every so often or crash but strong business
will come back and rather than worry about a temporary price decline
buy some more when that times comes.
dont worry about commentators who said buy and hold doesn't work, or it is a different time
and you got to constantly worry about your stock or hedge it or whatever, their jobs is to create
noises and generate activities.
things has not change in hundred of years, if the business deliver increase earning and dividend with time
then you don't need to worry about the stock price.
in fact volatility can be a good thing for you to aim and get into solid stocks and hold long term.
Best hedge for me is holding decent stock, write covered call when it run a bit hot and get some
income
