Interesting Casino analogy “land on Zero”. Roulette is a game of chance with fixed odds. Depending to the table 35-1 payout on any of the 36 numbers (37 with zero). When you buy a share for a reasonable time period you are investing and the payout is not fixed. Here we have in Mesoblast a company whose product works (Japan) what we don’t know is how many applications it will work on in the future (although there is a growing body of evidence that it is a lot!)
Shares can be volatile but please do not try and equate investing with gambling. The only beneficiaries of that are shorters who would like nothing more than shareholders to believe that this company’s future depends on nothing more than random luck. So when you sold you locked in your profit, good for you, your investment worked. If you now want to wait for Mesoblast to have approval in the USA before buying back in, that is a reasonable investment strategy. You will perhaps miss out on some or all of the movement on that news but you will be investing in a great company. Look forward to welcoming you back on board.
