STEX Bull Call Spread Strategy
STEX (Streamex Corp.), in the Financial Services sector, (Asset Management industry), listed on NASDAQ.
Streamex Corp., previously known as BioSig Technologies, Inc., officially assumed its new name on September 12, 2025, after completing a merger with Streamex Exchange Corporation. The company has since pivoted its core business strategy, moving from healthcare technology to specialize in the tokenization of tangible assets. A primary objective of this shift is to integrate the gold and broader commodities markets into blockchain technology. To facilitate this, Streamex provides robust, institutional-level infrastructure for asset tokenization, which is uniquely underpinned by a treasury denominated in gold.
STEX (Streamex Corp.) trades in the Financial Services sector, specifically Asset Management, with a market capitalization of approximately $31.7M, a beta of 1.86 versus the broader market, a 52-week range of 0.7-14.11, average daily share volume of 1.6M, a public-listing history dating back to 2025, approximately 5 full-time employees. These structural characteristics shape how STEX stock options price implied volatility around earnings windows, capital events, and macro-driven sector rotations.
A beta of 1.86 indicates STEX has historically moved more than the broader market, amplifying both the directional payoff and the realized volatility relative to an index-equivalent position.

Current STEX snapshot
As of June 29, 2026, spot at $0.79, ATM IV 121.10%, IV rank 21.24%, expected move 34.72%. The bull call spread on STEX 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 18-day expiry.
Why this bull call spread structure on STEX specifically: STEX IV at 121.10% is on the cheap side of its 1-year range, which favors premium-buying structures like a STEX bull call spread, with a market-implied 1-standard-deviation move of approximately 34.72% (roughly $0.27 on the underlying). The 18-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated STEX expiries trade a higher absolute premium for lower per-day decay. Position sizing on STEX should anchor to the underlying notional of $0.79 per share and to the trader's directional view on STEX stock.
STEX bull call spread setup
The STEX bull call spread below is built from the end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With STEX near $0.79, the first option leg uses a $0.79 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed STEX chain at a 18-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 STEX shares for the stock leg in covered calls and collars).

STEX thesis for this bull call spread
The market-implied 1-standard-deviation range for STEX extends from approximately $0.52 on the downside to $1.06 on the upside. A STEX bull call spread caps both the risk and the reward of a bullish position; relative to an outright long call on STEX, the spread reduces the cost basis but limits the maximum profit to the strike width minus net debit. Current STEX IV rank near 21.24% 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 STEX at 121.10%. As a Financial Services name, STEX options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to STEX-specific events.
STEX bull call spread positions are structurally moderately 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. STEX positions also carry Financial Services sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move STEX alongside the broader basket even when STEX-specific fundamentals are unchanged. Long-premium structures like a bull call spread on STEX 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 STEX chain quotes before placing a trade.
