Sharegain allows you to benefit from a new revenue stream from assets you already own. While your shares are out on loan, not much changes. You still retain all the economic rights for the shares you lend out, except for the right to vote. If your shares go up in value, you’ll still benefit (and naturally you’re also exposed to share-price falls). If there’s a dividend payment, you’ll still be entitled to it. Meanwhile, your securities could be out on loan, earning you rent.
