Any reliable Stock signal telegram/whatsapp channel ?

Stay away from those you will never make money. Get into stocks only when you are ready to learn else do Sips.

If they could really predict where a stock would go, they would invest money in it themselves and become billionaires, instead of selling or sharing stock tips with others. At best these stock signal groups are guess work and useless, and at worst they are pump & dump scams trying to manipulate some stocks in the market and make a profit for the people running the scam. Stay away from them.

How is Sovrenn?

Search for algopulse.ai and stockphoenix - Few of the reliable ones

Free advise. Stay away from such gurus and finfluencers. You will 100% loose money. If you really want to invest and don't have knowledge then let a sebi registered person or firm handle your money like Motilal Oswal. If you want to do it yourself stick with Index fund or mutual fund

Better learn so that even if you grow your money say in 2-3year with stock signals you don't lose it in a day and regret no understanding the reason for it.

Me. I only charge 5000rs per signal (no profit guarantee (also need 1lakh advance))
