Last year, Smita Patel lost 500,000 rupees ($11,400) of her personal savings in a day on the Indian stock market.

Since then, not only has she recouped her loss but is in profit to the tune of 250,000 rupees ($5,700) due to a share market surge that shows no sign of slowing down.
"I have never made money in the markets, from the time I started investing more than 10 years ago. This is the first time I have made any profits and now I am happy to say I am a gainer."

I have learnt to use the words 'not only' to combine with the words 'but also'. In the above the words 'not only' combine with the word 'but'. Would you agree with it?
The usual combination is as you say. "not only ... but also ...".
Nevertheless, it is not a hard and fast rule. The omission of "also" is not really objectionable.
