Read an article breaking down five small-cap tech and aerospace stocks. All five are currently unprofitable and carry high risk due to cash burn and share dilution. RKLB (Rocket Lab): The most established of the group. They need funding for their new Neutron rocket. Trading at a 67 price-to-sales ratio with some recent share dilution. IONQ (IonQ): Quantum computing. They have $3B in cash but reported heavy operating losses. They are diluting shareholders to fund operations, with share count up 72% since 2024. OKLO (Oklo): Developing small nuclear reactors for AI data centers. They sit on $3B in cash but still need to prove their designs are commercially viable. ACHR (Archer Aviation): Building electric air taxis. They have $1.6B in cash, giving them roughly 2.5 years of runway at their current burn rate. Share count is up 53%. ASTS (AST SpaceMobile): Direct-to-cell satellite coverage. Looks like the riskiest of the five. They hold $3B in debt and only have about a year of cash runway left based on current spending.
