+            cached = result.scalar_one_or_none()
+
+            if cached:
+                age = datetime.utcnow() - cached.updated_at


Using datetime.utcnow() is deprecated in Python 3.12+. Consider using datetime.now(timezone.utc) instead for better timezone awareness and future compatibility.

+            await self.finnhub.batch_update_quotes(db, symbols)
+
+            # Refresh positions to get updated quotes
+            await db.refresh_all(positions)


The db.refresh_all() method doesn't exist in SQLAlchemy. This will cause a runtime error. You should either iterate and refresh each position individually or re-query the positions after the batch update.

Suggested change

await db.refresh_all(positions)

for position in positions:

await db.refresh(position)

+        # Volatility (annualized standard deviation)
+        volatility = statistics.stdev(returns) * (252 ** 0.5) if len(returns) > 1 else 0
+
+        # Sharpe Ratio (assuming 0% risk-free rate for simplicity)
+        avg_return = statistics.mean(returns)
+        sharpe = (avg_return * 252) / volatility if volatility > 0 else 0


The Sharpe ratio calculation assumes 252 trading days per year, but the snapshots are not guaranteed to be daily. The calculation annualizes based on an assumption that returns are daily, which may not be accurate if snapshots are taken at irregular intervals. Consider calculating the annualization factor based on actual snapshot frequency.

+def get_finnhub_service() -> FinnhubService:
+    """Dependency to get Finnhub service."""
+    api_key = os.getenv("FINNHUB_API_KEY")
+    if not api_key:

+        )
+    return FinnhubService(api_key)
+

The get_finnhub_service dependency creates a new FinnhubService instance (with a new httpx.AsyncClient) for every request. This is inefficient and can lead to resource leaks since the httpx client is never closed. Consider using a singleton pattern or application lifespan events to manage the service lifecycle.

Suggested change

def get_finnhub_service() -> FinnhubService:

"""Dependency to get Finnhub service."""

api_key = os.getenv("FINNHUB_API_KEY")

if not api_key:

raise HTTPException(

status_code=status.HTTP_500_INTERNAL_SERVER_ERROR,

)

return FinnhubService(api_key)

def get_finnhub_service() -> FinnhubService:

"""Dependency to get Finnhub service.

"""

+            detail=f"Failed to calculate portfolio metrics: {str(e)}"


Exception details are exposed to the client via str(e) in the error response. This can leak sensitive internal implementation details or database errors. Consider using a generic error message for the client and only log detailed errors server-side.
