India's top telecom stock Vodafone Idea is also the biggest money loser

Although Vodafone Idea Ltd. hasn't made a profit since 2017, its shares have more than doubled in the past three months

For investors riding a rally in India’s wireless carriers, the best returns are coming from an operator that’s warned it may collapse without help from the government.

Although Vodafone Idea Ltd. hasn’t made a profit since 2017 and ended last fiscal year with a record $10 billion loss, its shares have more than doubled in the past three months. The surge has been driven mostly on optimism that the Indian government will rescue the beleaguered carrier after the Supreme Court burdened it with billions of dollars in fees.

Gains made by the penny stock outpaced the 51 per cent jump
