What is a long call on TLSA?
A long call buys upside exposure with a fixed maximum loss equal to the premium paid; profit accrues if the underlying closes above the strike plus premium at expiration.
Current TLSA snapshot
As of May 15, 2026, spot at $1.40, ATM IV 22.40%, IV rank 1.11%, expected move 6.42%. The long call on TLSA below is built from the same end-of-day chain, with strikes snapped to listed contracts and premiums pulled from the bid/ask midpoint at a 34-day expiry.
Why this long call structure on TLSA specifically: TLSA IV at 22.40% is on the cheap side of its 1-year range, which favors premium-buying structures like a TLSA long call, with a market-implied 1-standard-deviation move of approximately 6.42% (roughly $0.09 on the underlying). The 34-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated TLSA expiries trade a higher absolute premium for lower per-day decay. Position sizing on TLSA should anchor to the underlying notional of $1.40 per share and to the trader's directional view on TLSA stock.
TLSA long call setup
The TLSA long call below is built from the end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With TLSA near $1.40, the first option leg uses a $1.40 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed TLSA chain at a 34-day expiry; the cross-strike IV skew is reflected directly in the per-leg values rather than approximated. Quantity sizing assumes one contract per option leg (or 100 TLSA shares for the stock leg in covered calls and collars).

TLSA thesis for this long call
The market-implied 1-standard-deviation range for TLSA extends from approximately $1.31 on the downside to $1.49 on the upside. A TLSA long call expresses a directional view that the underlying closes above the strike plus premium at expiration, ideally with implied volatility holding or expanding to preserve extrinsic value through the hold period. Current TLSA IV rank near 1.11% sits in the lower third of its 1-year distribution, where IV often re-expands toward the mean; this favors premium-buying structures and disadvantages premium-selling structures on TLSA at 22.40%. As a Healthcare name, TLSA options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to TLSA-specific events.
TLSA long call positions are structurally bullish; the modeled P&L assumes European-style exercise at expiration and ignores early assignment, transaction costs, dividends paid before expiry on the stock leg (when present), and the bid-ask spread on the listed chain. TLSA positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move TLSA alongside the broader basket even when TLSA-specific fundamentals are unchanged. Long-premium structures like a long call on TLSA are particularly exposed to IV-crush risk through scheduled events (earnings, FDA decisions, central-bank meetings) where IV typically contracts post-event regardless of the directional outcome. Always rebuild the position from current TLSA chain quotes before placing a trade.
