Tonbo Imaging IPO: How Much Can Investors Gain?
At the current grey market premium of Rs 500, the estimated listing price can be Rs 1,200 per share. This translates into a potential premium of 71.43% over the upper end of the price band of Rs 700.
The minimum retail application comprises 21 shares, requiring an investment of Rs 14,700 at the upper price band.
If the shares list at the estimated price of Rs 1,200, the indicative gain on one retail lot would be Rs 10,500, excluding applicable charges and taxes. This estimate is based on the prevailing grey market premium and does not represent a guaranteed return.
