Be very careful taking advice about buying shares!
The stock market is posh gambling! No one can predict what will happen and sometimes it makes no sense at all. Like a company will release incredible results and everyone will sell, you would have expected it to increase.
Be wary of stock tips in newspapers etc, the writer normally has an interest! I got burned that way many a time in the beginning.
AIM shares that can now go in ISAs are very unpredictable! You can make huge gains but also huge loses! I have some that are 80% down and some that are 700% up!
If you want a punt, then choose a share involved with fracking. Igas or Egdon, both low price at the moment, have been much higher and have most potential for actual mining.
The best thing I can advise is a mix of funds and follow my Grandfather's investment strategy, which is:
SHARES
Buy only FTSE 100 shares, until you are comfortable with investing and losses! FTSE 100 aren't hit as badly as other markets.
Set up your account so it automatically reinvests dividends or uses SCRIP or DRIP schemes. Your investment will grow much bigger this way. Be aware you have to pay tax on dividends whether you take them as cash or reinvest them!
Buy only shares that have a high dividend yield, at least 3%
Buy from different fields, don't just buy all one type! Pharmaceuticals, Utilities, Supermarkets, Consumer Goods, Mining and Banking are the big ones.
Don't just buy once you have chosen your shares! Watch the price, look over the last 3 months at least, set up a buy limit, so when the price drops it automatically buys for you at that price.
Keep some money back and wait for a big price fall from a FTSE 100 company, happens at least once a year, wait till bottoms out and then when price just starts to rise again buy. I did this when Aviva had a profit warning, currently 55% up.
Be careful about buying new listing, while Royal Mail soared most don't! quite a few are 25-50% below listing price! I got burned that way several times!
Don't check your shares every day. It will just upset you. They go up and down!
I love this website for dividends yields, will help you choose shares.

FUNDS
Buy accumulation funds, your dividend is automatically reinvested.
I like these 3 funds for a beginner:
HL Multi-Manager Income & Growth Trust - Accumulation
This fund buys into many different funds so it spreads the risk
Legal & General UK Index Class C - Accumulation
This is a tracker fund so has low costs
CF Woodford Equity Income Class Z - Accumulation
Woodford has an amazing track record and has made a lot of people a lot of money, this is his new fund.
