If you cant form your own opinion when to buy or sell what are you doing in the share market?
I advise you spend more time educating yourself and don't gamble with your hard earned saving on the stock market thinking of easy money.
Invest in shares as you are part owner of a business and business takes time to mature, build market, fix up problems and you endure with its up and down and over a long period of time it will reward you with dividend and capital appreciation
Any other time ignores the headline, the price target, the doom day crew, the one that tells you to jump you fools
when you need the capital for whatever and need to cash out then do with your own will and conviction.
good luck and this weekend buy a few good books with your hard earn cash and cosy up with a nice cup of tea you will be a better investor in years to come
