Estimates from short-selling data. Levels are not predictions or trading recommendations.

Share lending and returned shares

Shares lent out (mostly to short sellers), new loans and shares returned each day. A return is either the lender calling the shares back (a recall) or the borrower handing them back, often after buying back a short. The published figures don't say which.

Shares on loan: 260.4K; 3.3% of listed shares
Loans, 5-day change: +2.3%
Loans, 20-day change: +9.7%
Returned, last 5 days: 10K
New loans, last 5 days: 15.9K
Short balance vs loans: 6.8%; How much of the lent stock is sold short. The higher it is, the more buying back a wave of recalls forces.
