Taking a loan to invest

Apologies if this isn’t the right place.

I have invested £1000 of my savings into stocks at the moment. I have a teacher who is sharing his knowledge and we have completed several transactions already, each making profit and I now stand just under £1500.

I have seen the evidence of the profit he makes for each transaction, but advises me that if I had invested more, I would be eligible for a larger quantity of different markets and transactions and therefore significantly more profit.

I can take a loan out from my current bank, to get to the next bracket for markets and transactions, and I can afford to pay the monthly instalments at present, even if I make no extra income. I have purposefully not invested all my savings and have enough for a rainy day as I didn’t want to have nothing left if the venture didn’t work.

The question is whether it is worth it to take the loan to get to the next bracket?

Also The only loan I have is my mortgage at present which I am overpaying on the monthly instalments anyway.

Send like a win-win if I can already cover the repayments, and I’ll be making stacks more but I’ve never had a loan except my mortgage, I don’t have a car in less or anything. I’ve always only bought stuff with what I have in the bank.
