We start from the observation that many investors do not actually have portfolios that are well aligned with what scientific research has suggested over the past few decades. Instead, investors get caught up in investing myths. The situation is reminiscent of the saga of Homer’s Odysseus, where many sailors went shipwrecked by following the beautiful chants of the sirens. We propose a solution lending from the wisdom of Odysseus. By adopting an easy-to-implement, evidence-based approach, investors keep the course and can avoid falling for investment myths and financial shipwreck.
